  • the bolt can be pre-fixed by self-locking of the bolt in the through-opening by means of the at least one lug.
  • the lug can come into frictional contact with the one external thread turn or external thread turns of the bolt if it is oversized. Due to the lower strength of the lock washer, the nose can be deformed without damaging the bolt, in particular the external thread. For example, a surface of the nose is smoothed. As a result, the oversize of the lug is reduced to an oversize that causes the frictional connection and is effective.
  • the locking washer can have a plurality of lugs, for example two lugs, in particular three or more lugs, for pre-fixing the bolt by means of self-locking on an inner circumference of the through-opening.
  • the lugs are formed, in particular embossed, on the inner circumference of the through-opening with a height offset relative to one another.

As a result, the oversize of the lugs is reduced to an oversize that causes the frictional connection and is effective. In other words: Due to the oversize of the lugs, when the locking washer and bolt are joined, plasticizing and a frictional connection between the bolt and locking washer occurs.
  • the lugs can be distributed symmetrically on the inner circumference, in particular formed or arranged. For an axially symmetrical pre-fixing of the bolt in the locking washer, three lugs are preferably provided symmetrically distributed on the inner circumference of the through-opening.
  • the lock washer can also have two opposite lugs. This arrangement of the bolt in the lock washer with three symmetrically distributed lugs is also referred to as the three-point position of the bolt in the lock washer.

In other words: When assembled, the bolt is pre-fixed and held in the lock washer by self-locking of the external thread and internal thread. For this purpose, the external thread pitch of the bolt is different from the internal thread pitch of the through-opening of the locking washer.
  • the lock washer can be designed as a washer.
  • the locking washer can have a square or rectangular outer contour.
  • the lock washer can be a comparatively have small wall thicknesses, for example from 2 mm to 5 mm, with strength being able to be achieved by tempering.
